Q28IP Connectivity
Refer to the exhibit. If you configure a static default route on the router with the command `ip route 0.0.0.0 0.0.0.0 10.13.0.1 120`, how will the router respond?

You really have to notice the "120" here so you don't miss the right answer...

and this is exactly what i missed

Selected Answer: D
Floating static route with AD 120 is a backup to OSPF route. Won't be used until OSPF route goes down.

Tricky one can't miss manually adding the 120 AD....

This is also the method that people use for setting a floating route with ad higher than the default route
4
the 120 AD makes it a floating static route --- which is added for redundancy in case the OSPF fails.
4
specifying te administrative distance of 120 means it's a route that will only be used when teh OSPF route is removed, since it has an administrative distance of 110 and therefore should take precedence

i thought i was going crazy, thx

Selected Answer: D
Because Static route as default has 1 AD but it was manually configured to 120 which is greater than 110. So, it won't be considered until former OSPF route is not removed.

OSPF AD 110

Selected Answer: B
The best way to answer this vague question is to eliminate the answers which are definitely wrong and these wrong answers are: A, C, E, F which leaves out B and D as the only possible anwers. Since D is a no brainer we have to focus on why B could be right. R1 which is the DR indeed won't establish an adjacency with R3. Adjacency means the that the 2 routers would be in Full state which is the state they will not reach. They will only be able to reach the 2-way state. The routers will be able to have a neighbor relationship but will not form a neighbor adjacency.

I think someone needs to explain to me again about floating static. OSPF already has AD of 120. if you configure a floating static isn't supposed to be 121???????????
